XP to Win7 upgrade and Ram?
 

Anyone offer advice on OS upgrade for my current XP?

I have a Win 7 64bit upgrade disc but only have two memory slots with 2 x 2Gb sticks installed. If I installed it I would then have DX10 but my memory would be seen as 2Gb. Would it be better to wait untill a 64bit patch comes along and run with 2GB or go for Win7 32 bit and have DX10 + 4Gb?

I don't understand why you think Win7 64 would only 'see' 2Gb of RAM. I have just upgraded from XP with 4GB RAM - where XP only saw 3.4GB - to Win7 64 where it sees all of it.

The Win7 32bit will behave like your WinXP (32bit)
It can only address 4Gb TOTAL including the RAM on your GPU

The Win7 64bit does not this limitation so you wll be able to see full 4Gb RAM.

not sure about the above in detail but what i have found out thus far is when i got the game i tried the game on all 3 of my OS's

Xp 32bit home sp3 = quite good stable platform with decent performance
Vista 64bit sp1 = aload of cack not really going to say much more
Windows 7 32bit = outstanding performance with a few jitters over the land

i would definitely state that windows 7 OS is the better OS to use on this game

Ah, thanks, I thought that 2 x 2GB sticks (4GB) on a 64bit OS was seen as 2Gb. I must have misunderstood.

+1

I'm actually impressed.

Just upgraded xp sp3 --> Win7
Big changes.

Game no longer crashes, performances are still a bit lowish and stutters a lot but at least I can play the game... I mean, I can take screenshots ! lol

My "Old" rig :
CP Intel E6750
Ram 4 Gb
GPU Ati 4890

Same here. It was hopeless on 32-bit XP, on 64-bit Win 7 it's better. Still far from what it should be, of course, but at least I can fly around a bit now without graphics problems.

OK, I have a 150GB partition on my current XP install for various files and copies of Il1946, etc. I could install Win7 on this and create a dual boot easily thus keeping XP for my current Il946 installs.

I am completely new to steam, are there any procedures for uninstalling Steam on the XP partition once I have Win 7 installed and ready?

Honestly, stop being a Noob. Delete Xp, IL-2 Sturmovik runs on Windows 7 (once you get it installed) from the disk.

XP is pre dated slow, and slowly decreases in peformance over time. Some how I doubt ul be able to run Cliffs of Dover.

Did do an upgrade of fresh install?? Ive heard a lot of people have trouble with upgrading and end up doing a reformat and full install of win7
